The original price is $4.50 because when you multiply it by 50% you get $2.25
The electric currents and magnetic materials have an
effect called magnetic field. This magnetic field is specified with its
direction and magnitude. The magnitude is the strength of the field.
the magnetic field at a distance r from a
long straight wire carrying current I can be calculated with the
equation:
B = μ I / 2 pi R
where <span>μ is a constant, I is the current and R is the radius. </span>
Answer:
11m/min
Step-by-step explanation:
slope of the line = velocity of the turtle
slope = y/x
= 55/5
=11
